Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2024-5700)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Buffer overflow (CVE-ID: CVE-2024-5696)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing the text in an <input> tag. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Security features bypass (CVE-ID: CVE-2024-5693)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to Offscreen Canvas does not properly track cross-origin tainting. A remote attacker can access image data from another site in violation of same-origin policy.
4) Security features bypass (CVE-ID: CVE-2024-5691)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an error when handling the X-Frame-Options header. A sandboxed iframe could have presented a button that, if clicked by a user, would bypass restrictions to open a new window.
5) Information disclosure (CVE-ID: CVE-2024-5690)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output about the external protocol handlers. A remote attacker can perform a timing attack and gain access to sensitive information.
6) Use-after-free (CVE-ID: CVE-2024-5688)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error during JavaScript object transplant. A remote attacker can trick the victim to visit a specially crafted website, trigger memory corruption and execute arbitrary code on the system.
7) Improper Restriction of Rendered UI Layers or Frames (CVE-ID: CVE-2024-5689)
The vulnerability allows a remote attacker to perform phishing attack.
The vulnerability exists due user confusion when taking screenshots with Firefox. In addition to detecting when a user was taking a screenshot (XXX), a website was able to overlay the "My Shots" button that appeared, and direct the user to a replica Firefox Screenshots page that could be used for phishing.
8) Use-after-free (CVE-ID: CVE-2024-5694)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a use-after-free error in the JavaScript engine. A remote attacker can trick the victim to visit a specially crafted website and read memory in the JavaScript string section of the heap.
9) Reachable assertion (CVE-ID: CVE-2024-5695)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion. A remote attacker can trick the victim to visit a specially crafted website, trigger an out-of-memory condition and crash the browser.
10) Information disclosure (CVE-ID: CVE-2024-5697)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A website was able to detect when a user took a screenshot of a page using the built-in Screenshot functionality in Firefox.
11) Improper Restriction of Rendered UI Layers or Frames (CVE-ID: CVE-2024-5698)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to an error when processing data-list. By manipulating the fullscreen feature while opening a data-list, an attacker could have overlaid a text box over the address bar. This could have led to user confusion and possible spoofing attacks.
12) Input validation error (CVE-ID: CVE-2024-5699)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to the way Firefox handles cookie prefixes. Cookie prefixes such as __Secure were being ignored if they
were not correctly capitalized - by spec they should be checked with a
case-insensitive comparison. This could have resulted in the browser not
correctly honoring the behaviors specified by the prefix.
13) Buffer overflow (CVE-ID: CVE-2024-5701)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
